Hello all.

Can somebody help me with my Canon i950.I have been trying to print a picture of a dog and the black parts of the print are coming out a strange shade of green.I normaly print on Ilford smooth gloss and my printer has always been ok until today.So I tried printing on Canon photo paper pro to see if that made any difference.I used the print advisor in the driver and still got the strange colour in the deepest black parts.I print stright from photoshop with document set to adobe RGB (1998) and print space set to adobe RGB (1998).Also done a nozzel check and that was ok.Any ideas?

I don't know this printer, I use an epson 2100 but I'm pretty sure the print space should be 'printer colour management'/perceptual. That's what you should use with my printer and, using ICM in the printer dialogue produces prints that are identical to on screen.

Sorry I use epsons, however another idea look in PS edit/color settings and see what you have input there.

I also use Epsons and with them you often get a greenish cast to blacks, its called metemerism, a known fault with dye based printers. Epson's archival and ultrachrome inks don't seen to exhibit this problem as much. I'd guess its the same with your Canon printer.

It usually appears when I don't make many prints during some days. With my Epsons then I also receive a greenish-touch in the blacks. Usually all inks don't come to the paper. Doublecheck and clean your cadridges. Maybe there are dry nozzles.

My one and a half year old Epson C82 is the worst printer I ever had. I also own an 8 year old (!) Stylus Photo which is by far better, a Canon BJC 7000 Photo and a the new cheapo (€50) Canon Pixma ip1500.
The strange with the C82 is that it has a very very strong magenta cast whatever settings and papers I use and the only thing that save it from throwing out of the window is the speed in texts.
Trying to print proofs from CS and Corel Draw is a comedy and tragedy together.
This has nothing to do with the computer setting, all other printers are OK.

But now I never use inkjets for printing my pictures because luckily I'm very satisfied with the labs I cooperate.
Prints that come out from well calibrated professional Fontiers, Noritsus and Dursts are by far superior in every term.

Hi all.
Thanks for all your replies.I think i have solved my problems.I ran the head cleaning utility and aligned the print heads and now all seems ok.I dont know why this worked because my nozzel check pattern was ok before i ran the clean utility.Anyhow i just printed a 10 x 8 and its fine.I wonder if it would be wise to run the head clean and print head alignment utility once a month just to keep everything as it should be.What do you think.

Print head alignment is very important and often overlooked by users. Jon Cone, and others, actually recommend you do a head alignment every time you change papers as paper thickness is an issue when you're spraying microscopic dropletts of ink.

Hi Mike.
I only print with ilford smooth gloss but still wonder if it will be wise to clean and adjust once a month and also when replacing inks.

Rob, I do a nozzle check each day I plan to print and several in a row after installing new ink carts just to make sure the path is free of air after unseating the old carts. If the pattern is broken I clean the heads. I'm using Epsons but assume you have similar utilities with a Canon.

Another thing to keep in mind is relative humidity. Too dry an environment will dry print heads if not used daily. When I first moved to Hawaii I lived and worked in a non air conditioned space. I never had an issue with dried heads as its always pretty humid here. The past year has me in an air conditioned space and I am having more of a problem now as the AC keeps the space too dry. If you're in a cold climate, forced heat is very dry.

Even if you only use one paper, its a good idea to do a print head alignment for that paper at least once. You can't trust that the (+) (-) paper lever is accurate for your paper, those are leftover from desktop document printing with coarse adjustments for bond and envelope thicknesses. I'd recommend wasting a few sheets of your photo paper to do a head alignment. The improvement may be minimal, but its there.
